“Next Generation Optical Network”
• Main objectives
– To define requirements, scenarios and architecture for core and
metro optical networks;
– To study advanced traffic engineering and resilience techniques;
– To specify and to implement a traffic engineering algorithm;
– To realize traffic engineering algorithm performance and
scalability tests.

Network requirements
-
Architectures reducing OPEX/CAPEX and providing revenues
opportunities through new network services;
Fast automatic provisioning;
Automatic Network Discovery;
Separation of service management/control from the underlying
multi-service network;
Efficient and standard management and control solutions for endto-end network services;
Multi-vendor interoperability;
Multi-layer Traffic Engineering;
Multi-layer Survivability.
